If you ever find yourself in Washington, and need suggestions on what to see, I highly recommend the U.S. Botanic Gardens. It is very easy to find, you can see all of it before your non-gardening companions lose interest, and it offers a breath of sanity sorely needed just a few hundred yards away and up The Hill.
